SMOKING-PIPE.

nearly perfect combustion to' thereby con- $111116 the poisonous matter in the tobacco; and to provide a construction and arrangement of parts designed to prevent the formation of deleterious and objectionable deposits which in the ordinary pipe are formed in the "bowl and stem and drawn into the mouth of the smoker; as well as to provide a construction whereby a thorough cleaning of the pipe is facilitated.

The above and other objects are attained by the novel features and combination of parts hereinafter particularly described and claimed.

Reference is to be had to the accompany ing drawings forming a part of this specifia cation, it being understood that the drawings are merelyillustrative of one example of the invention.

Figure 1 is a longitudianl vertical section of a smoking pipe embodying my invention;

Fig. 2 is a plan view thereof with the mouthpiece partly in section;

Fig. 3 is a fragmentar plan view with the upper movable part 0 the main bowl in the raised position and part of the removable and auxiliary bowl broken away;

Fig. 4: is an enlarged front view of portions of the fixed and movable main bowl sections and showing the latch means for the movable bowl section. 2

Fig. 5 is a longitudinal vertical section of the front portion of the pipe illustrating a modification.

In carrying out my invention in accordance with the example Figs. 1 to 4, the main bowl includes a bottom, relatively fixed, section 10 having a stern section 11 thereon and an upper bowl section 12 hinged as at 13 adjacent to the stem section to swing-into position on the fixed section 10 or swing to a raised position as indicated in dotted lines, Fig. 1 and shown in full lines in Fig. 3. The movable main bowl section 12 is secured by a suitable latch means, there being shown a, latch bolt 14 swingably secured at Specification of Letters Patent.

its lower end 15 to a hin e plate 16 on the lower bowl section 10, said olt being adapted to enter theslotted flange 18 on a catch plate 17, secured to the bowl section 12, the upper threaded end of said latch bolt being ada ted to receive a cap nut 19 preferably havmg a slot 19 to receive a screw driver or like tool for tightening the nut.

The main bowl composed of sections 10 and 12 with the fixed stem section 11 is in practice formed of metal and within the lower bowl section 10 I provide an auxiliary removable bowl 20 of porcelain, clay, or other suitable material to constitute when in place a lining for the metal bowl section 1.0. The bowl 20- has a smoke passage 21 at its forward side produced by the main wall of the bowl and by a transverse partition 22 curving rearwardly so that the smoke passage 21 curves toward the rear of the bowl and terminates adjacent to the bottom thereof. In the auxiliary bowl 20 and rearward of the partition 22 is a horizontal screen 23 of copper or like metal which is removably secured in place by suitable means such as a split rin 24 to facilitate the thorough cleaning of t e auxiliar bowl and the screen, and to ermit of readi y renewing the screen should it become necessary. A smoke passage 25 leads rearwardly from the auxiliary bowl 20 above the screen 23 in register with the smoke passage 26 in the main bowl section 10 and leading to the stem 11. With the described arrangement smoke drawn downwardly from the upper main bowl section 12 into the passage 21 will be permitted to expand rearward of the partition'22 and in being drawn to the stem will be disseminated over the surface of the screen 23. Nicotin .or the like will tend to collect in the bottom of the auxiliary bowl 20 and the smoke will be further relieved of nicotin by deposit of the latter on the screen 23.

The auxiliary bowl 20 is covered by a plate 27 which has perforations 28in register with the smoke passage 21. Sa1d late 27 is held in position on top of the auxl iary bowl 20 by the movable main bowl section 12 which is provided with a suitable member or members to overlie the said plate, there being indicated a flange 29 present ng a shoulder on said bowl section 12 overlymg the edgeportion of said plate. Thus, the auxiliary bowl and its cover plate are held in place by the bowl section 12.

The stem .11 has an enlarged bore 30 in which saliva ma' collect and be prevented from reaching t e bowl through the assage 26. Aclean-outdplug 31 is rovide in the stem section 11 a jacent to t e forward end of the bore 30. A suitable removable stem section 32 engages in any suitable manner with the outer end. of the stem section 11, there being shown a reduced end or tenon 32 on said stem section 32 fitting within the rear end of the stem section 11. The mouthpiece has a plurality of smoke outlets 33 designed to have a cooling effect on the smoke to a greater extent than a single assage. Disposed lon itudinally within t e stem sections 11 an 32 is a tube 34 which may be formed of glass or other suitable material, said tube is secured at its forward end in an suitable manner asat 35 in the bowl sectlon 10 at the junction of the stem section 11, the said tube in the illustrated example being threaded to engage the bowl 10. At the outer end the tube 34 is centered by projections 36 on the interior of the removable stem 32.

Provision of the smoke passa e 21 adjacent to the front wall of the bow instead of drawing the smoke directly into the stem,

tends to produce a cool and leasing smoke, particularly in connection wlth the enlarged chamber provided in the bottom of the bowl and 'to which said smoke passage leads. Also, the screen 23 in addition to causin a deposit of the nicotin and other matter ta es up and radiates much of the heat in the smoke.

The stem section or mouth iece 32 forms a a continuation of the saliva c amber 30 and the tube 34 terminates short of the outer end of the mouthpiece and thereby not only is the saliva prevented fromenteringthetube 34 but any nicotin that may fail to collect in the bowl 20 or on the screen 23, will ass from the tube 34 into the exterior sa iva chamber of the stem and be prevented from reaching the mouth of the smoker. A thor ough cleaning of the pipe is possible since by swinging the upper main bowl section 12 to the raised position, the plate 27 and the auxiliary bowl 240 with its screen23 may readily be removed for separate cleaning. Similarly, the stem 32 and tube 34 may be removed and pro erliy cleanedwith facility, and the removail o the clean-out plug 31 permits of the chamber 30 being thoroughly cleaned.

The main bowl is preferably divided on an oblique line as shown instead of parallel with the top of the bowl, and the auxiliary bowl 20 similarly, has a slopin top, the

arrangement servlng to permit 0 the ready removal of the auxiliary bowl and the plate 27 without cutting away any of the incrusted matter in the up er part of the bowl.

In the exam le 1 lustrated in Fig. 5, the main bowl 10 as an open bottom 1n which the auxiliary bowl 20 is inserted and corresponds in all respects with the form shown in Figs. 1 to 3 including its cover plate 27 with the smoke outlets 28 as well as the smoke passage 21 and screen 23 and ring 24. Also, the auxiliary bowl has a smoke outlet 25 to register with the smoke the bowl 10 at the juncture o the stem 11*. The auxiliary bowl ma be held in the main bowl 10" in any suitab e manner as by having a tight fit therein so that it will securely retain its position while being removable when desired. The main bowl 10 may have the flange 29 or other projection or projections to resent a shoulder against which the top of t e auxiliary bowl engages.

I would state in conclusion that while the illustrated examples constitute practical embodiments of my invention, I do not limit myself strictly to the mechanical details herein illustrated, since manifestly the same can be considerably varied without departure, from the spirit of the invention as defined in the appended claims."
